Method of making chewing bones for pets

Abstract

Chews for pets are made from sinews or tendons of cattle and other livestock by the method of cooking the tendons and sinews, followed by the removal of meat and fat, and then baking at a temperature of at least 200° C. until they are completely or substantially completely hardened.

I claim: 
     
       1. A method of making chewing bones for pets comprising: cooking a batch of tendons of cattle, cows, bulls, oxen, horses and ponies in an aqueous solution for a period of approximately five hours at a temperature higher than 90° C.;   removing substantially all meat and fat from said tendons;   heating said batch of tendons to approximately 240° C. in a period of approximately 1.5 hours;   lowering said temperature from approximately 240° C. to approximately 190° C.;   maintaining said temperature of approximately 190° C. for approximately 1.5 hours to obtain a substantially 90% hardened batch of tendons; and then   baking the remaining unhardened tendons of said batch for an additional period until substantially all of the tendons of said batch are hardened.   
     
     
       2. A method as claimed in claim 1 wherein: said tendons comprise taddywacks.   
     
     
       3. A method as claimed in claim 1 wherein: said tendons comprise silversides.   
     
     
       4. The method as claimed in claim 1 wherein: said step of cooking comprises boiling the tendons.   
     
     
       5. The method as claimed in claim 1 wherein: said step of cooking comprises steaming the tendons.   
     
     
       6. The method as claimed in claim 1 and further comprising: between said meat and fat removal step and said heating step, shaping the tendons into a desired shape.   
     
     
       7. The method as claimed in claim 6 wherein: said shaping comprises pressing in a mold.
